The IMSAI 8080 was probably the first clone in the PC world. The unprecedented success of the MITS Altair prompted many to enter the Personal Computer arena with competing systems to capitalize on the new market and MITS inability to fulfill all of its orders in a timely fashion.
The IMSAI 8080 gained further fame when it stared in the 1984 film, War Games, alongside Matthew Broderick and Alley Sheedy.
The inside of this 8080 case is as clean as the day it was built. Only about half of the 22 slots on the motherboard are populated.
